Harvey Tool 35615-C4 Ball End Mill 0.015 in 3 Flute Carbide

Product Description

The HARVEY TOOL 35615-C4 is a miniature solid carbide ball end mill designed for high-precision milling of non-ferrous metals. With a 0.015 inch cutting diameter, a 0.022 inch length of cut, and a 30-degree right-hand helical flute geometry, this single-end tool delivers accurate profiling and contouring at micro-scale. The amorphous diamond PVD coating reduces friction and extends tool life when cutting aluminum, copper, brass, and other non-ferrous materials. Three helical flutes provide a balance of chip evacuation and edge strength at this diameter range. The extended reach design with a stub flute configuration makes it well suited for deep-cavity and fine-detail work where standard reach tools cannot access the feature geometry.

This end mill is built for miniature milling applications in aerospace, electronics, medical device, and precision mold work where tight tolerances and small feature sizes are required. The 0.125 inch straight-cylindrical shank fits standard collet chucks on CNC machining centers and high-speed spindles. The 2.5 inch overall length provides clearance for moderately deep setups while the 0.187 inch reach length and 0.165 inch neck length keep deflection low. It is rated for roughing and finishing operations on non-ferrous materials under the ISO N workpiece classification.

Key Features

• 0.015 inch ball end diameter with plus or minus 0.0005 inch diameter tolerance
• Amorphous diamond PVD coating for extended tool life in non-ferrous metal cutting
• 30-degree right-hand helix with three helical flutes for efficient chip removal
• Extended reach, stub flute design accesses deep cavities while limiting deflection
• Single-end solid carbide construction for rigidity at miniature diameters
• Rated for both roughing and finishing passes on ISO N non-ferrous materials

Compatibility

Designed for use with standard 0.125 inch collet systems on CNC machining centers and high-speed spindles. Intended for milling non-ferrous metals including aluminum, copper, and brass alloys. Part of the HARVEY TOOL Miniature End Mills Ball Long Reach Stub Flute series.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Secure the shank in a precision collet or end mill holder to the full recommended grip length before operating. Always verify spindle runout before running miniature diameter tools, as excessive runout will rapidly degrade the cutting edge at this diameter. Do not use in ferrous materials, as the amorphous diamond coating is not compatible with ferrous workpieces.
